' This invention relates to devices used for *y turnably sup-porting shafts and the like, as

in journal boxes,V p .L i

One of the objects of this invention is to reduce the friction in a journal box to amini mum.

Another object is to provide a roller in a i.

l journal box with a carrying portion of larger diameter than the carried portion.

Another object is to-provide rollers spaced from one another and disposed so that a shaft or the like member can be supported between oppositely disposed rollers, so yas to rest equally on and between'theoppos'itely disposed rollers. Y j l Another'object is to provide supporting i blocks for the rollers with Vthe supporting sur- 'which the molds for the Vto be rotated.'A Y e e `Fig.` 2 is a fragmentary detail cross section face slanting at about right angles to the direction of supportfor a shaft or the like mein-l ber between oppositely disposed rollers.

Another obj ectis to provide a yielding sup,- portbelow the bearing box. 'n

Other objects will appear from the follow-` ing description and appended claims as well as from the accompanying' drawing, in Whiche Fig. l is a somewhat diagrammatic illustration of an arrangement by which concreteV pipes are supported on rollers whilethe con# crete mixture may be fed into the rotating molds supported by the rollers, indicating also the position of bearings or journal boxes on a frame structure to 'support therollers on concretepipes rest through a supporting-'roller and journal'box with rollers and supporting blocks designed i to illustrate the invention.

Fig. 3 is a side elevationof the j journal box Fig. 4; is a cross section on line 4 4 of Fig. is

Concrete pipes are efficiently poured and manufactured under centrifugal principles in the manner roughly outlined in Fig. l.

The molds Gare provided with rims supported on rotating wheels 8.

Molds of this sort can be supported in a number according to the number of wheels mounted on a common frame 9.

Wheels 8 are provided on the opposite sides J opposite ends o f the molds 6. n s ,1

4 Providing four pairs of `wheels 8 allows a ANGELES, cerimoniale, Assrenon To wnsrgnnn concentra rire coifiriinr, or Los ANGELES, oarrroanra. s 'f placing of three molds as illustrated'in Fig-[1 or, providing live` p airs of Wheels 8, four molds may be supported, and accordinglyvmore or less molds may be supported dependingl on the number of wheels provided on a commonl frame.

f @ne pair of thelwhole setY of wheels in a common fijamejis provided lwith driving inea-ns, Aas'by a Vbelt l()l and motor 11 roughly indicated and outlined in the drawing. `How-` f ever, other driving ineans'may bve-provided to suit the conditions ofa plant where suchl l' structures' are used Vand depending.y upon requireinents 4and various vconditions of dif` ferent localities and the Vpurposes for which suoli structures may be used. s

For concrete pipes it is Vsufficient one pair of VVwheels whereby, when a mold -6 1 is placedl in a position as illustratedin Fig. l1, tlie 'next following pair` is,Y automatically caused to rotate and thereby'serves to transmit rotating mot-ions, to rotate the several concrete moldsv placedlon the-several pairs of wheels in a ymanner illustrated lin Fig.; 1.

f It is not necessary that the vfirst vfor any. other of the following pairs of wheels are interconnected by a common shaft since any' mold placed on top of the wheels 8 tends-to. serveas a driving force or. interconnec'ting,y

means between the wheels on the opposite endsv of the mold. The driving of one ofthe to drive Sey wheels on one side of thewhole structure-,isi I therefore sufficient as a driving means for the wholemultitude ofy wheels otherwise absolutely'unconnected.

lEach ofthe wheelsSfis therefore prefere ably mounted adjacent toa journal box. :A

vjournal box as indicatedfatvl2 is illustrated .l i more fully detailed in Figs2, 3,14, and 5j The p y l j .box serves'to enclose blockslfand the rolla longitudinal section'on line 5 5 l i Y ersle.- .s l i e A shaft 15 is .provided to suppgrt the wheel 8.' vvThe shaft l5 extends thereforeV from the wheel 8 into and through the adjacentjourf nal box. '.Thershaft lis provided with colek is maintained in its posiin providing u1@ @911m 1e with' the double annularend faces or shoulders 17, these collarsV are ,made exchangeably to assure durability and satisfactory running on the rollers 14.

While the Tunning portions 18 are shown to rest yon the'rollers, as especially illustrated in Fig. 4, the collars `can be turned around on the shaft so that the running faces 19 of the two collars come to rest on the rollers 14.

A roller 14 consists of the centralv supported portion 20 and the two flange-like or wheel-like end supporting portions 21. The central portion 20 'serves to carry and support the end portions 21 and is therefore mounted in a trunnion box 13. Y The end portions 21 are spaced on all sides within the jouriialbox 12, and a special collar portion 22 is provided to bear against the' op-posite sidesV ofthe block 13 as illustrated in Fig. 4.

The larger diameter of the end portions 21 in relation to the smaller diameter of the trunnion or central portion 20 provide for an easy turning-of these rollers byreducing the friction on account of the small vbearing Ysurface on thecomparatively small trunnion or central portion 2O'v for the larger roller wheels or endY portions 14.

The blocks 13 are `held adjustably and ex-v changeably within-the box 12. A shoe or Ytop block 25 serves to rest on the top of the collars 16 between the oppositely disposed 'faces 17 of the collars 16 on the shaft 15.

This shoe 25 is disposed in the cover plate i V26 havingl arpin 27 by which the shoe may adjust and align itself into proper position overthe shaft 15y between the two collars 16.

The whole journal box is mounted swingably and pi'vota'lly on a supporting block 28.

This vsupporting block is provided with inclined faces 29 serving-,to allow a slight tilting of the whole journall box whereby the journal box may allow an aligning of the shaft 15 in a vertical planepin relation to other cooperatively disposed journal boxes.

A bolt 30 is disposed through the bottoni ofthe journalY box and through the'suppoi'ting block 28 by which Vthe journal box isV pivotally held to 'align itself in a. horizontal planeinrelation toother cooperating ournal boxes. Y

' The supporting block 2S is provided with a round boss 31' around which the whole structure may swivel.v

Each block 13 is of ysomewhat triangular *formV with the bottom face 3 2 to support the.

block, a comparatively large end face 33 and another comparatively small end faceV 34 for holding the block .against4 endwise move- ,ments,j andaninclined face 35 with, a semicircular recessserving as a bearing for the central or trunnion portion 2O of a roller.

Oppositely disposed blocks 13 are therefore disposed with their inclined faces and bearing recesses iii opposite directions to receive and holdthe shaft 15 and thereby counteracting the pressure from the shaft to be' sustained from the opposite ends of a journal box of this type.

Having thus described myr invention, I.

nsV

posed blocks being disposed to face centrally in relationto the housing, the said trunnion blocks having squarely shaped surfaces on the remaining sides by which the-blocks can be exchangeably' fitted to bring the inclined surfaces with the bearing portions into accurate operative relation to one another and rollers disposed in said bearing portions of i said blocks and removable from said inclined Y faces of the blocks.

2. In a journal box, a housing having a hole in a vertical direction` through the bottom to'receive a bolt around whichthe housing may swivel7 the housing having afrec'- tangular recess inthe bottoni` side crosswise to said holeto receive a guide block by which `the journal box can be slidingly supported for "sliding movements in a horizontal plane. 3; In a journal box, a supporting block of rectangular outline in `a horizontal plane having .a hole in a vertical plane to receive a bolt around which the block may swivel, andv around boss projecting from the undersidev of the block concentrically with said hole furnishing .additional guiding means forthe swiveling movements ofthe block.
